What Every Arabi Homeowner Needs to Do for Their Plumbing Before Hurricane Season
The moment tropical storm warnings appear on the radar you have a narrow window to protect your Arabi home from catastrophic plumbing failures. The New Orleans Sewerage & Water Board’s combined sewer system and the area’s below-sea-level elevation create unique vulnerabilities that standard hurricane prep guides ignore. This guide walks you through the critical steps to prevent backflow flooding, contaminated water supply, and sewer line breaks before the next storm hits.

Understanding Arabi’s Plumbing Vulnerabilities
Arabi sits in a flood-prone zone where the water table sits just inches below the surface. During heavy rainfall the S&WB’s drainage system can become overwhelmed causing water to back up through floor drains and toilets. The area’s predominantly slab-on-grade construction from the 1960s and 1970s means many homes lack the elevated plumbing fixtures that could prevent sewage backflow. The clay-heavy soil expands when saturated putting stress on buried sewer lines that were often installed with minimal bedding material.

Pre-Storm Plumbing Checklist: 5 Critical Steps
- Locate and Test Your Main Water Shut-off Valve
The shut-off valve is typically located near the water meter box in your front yard. Turn the valve clockwise to ensure it moves freely. If it’s stuck apply penetrating oil and try again. A stuck valve during a hurricane could leave you unable to stop contaminated water from entering your home’s supply lines..

- Inspect and Clean All Floor Drains
Pour several gallons of water down each floor drain to ensure they’re flowing properly. Remove any visible debris from drain covers. Floor drains are the most common entry point for sewage backflow during S&WB system overloads. Emergency Drain Cleaning Services for Metairie Homeowners and Businesses.
- Verify Sump Pump Operation and Battery Backup
Test your sump pump by pouring water into the pit until the float activates. Listen for the motor to engage. Check battery backup by unplugging the pump and verifying the battery-powered backup activates. Replace batteries that are more than two years old.
- Secure Outdoor Plumbing Fixtures
Disconnect and store garden hoses. Install foam insulation covers on outdoor faucets. Check gas line connections for corrosion and apply pipe thread sealant if needed. Loose outdoor fixtures can become dangerous projectiles in high winds.. Read more about Why You Should Install a Smart Leak Detector in Your CBD Vacation Rental.
- Install or Test Backwater Valves
Backwater valves prevent sewage from flowing back into your home through floor drains and toilets. If you don’t have one installed now is the time to add it. If you have one test the flapper mechanism by pouring water into the drain and watching for proper closure.
The Critical Role of Backwater Valves in Arabi Homes
Backwater valves are your primary defense against sewage backflow during storm surges and heavy rainfall. These one-way valves allow water to exit your home but prevent contaminated water from entering. In Arabi’s flood-prone areas the valves should be installed on the main sewer line where it exits your home. The valve contains a flapper that closes when water pressure from the street exceeds pressure from your home. During a S&WB system overload this prevents sewage from backing up through your drains..

Testing your backwater valve is simple but critical. Pour five gallons of water into your lowest floor drain and watch the valve. The flapper should close completely preventing water from backing up. If you see water rising in the drain or the flapper doesn’t seal properly call a licensed plumber immediately.

Managing French Drains and Catch Basins
Arabi’s residential lots often include French drains and catch basins designed to handle normal rainfall. Before hurricane season clean all drain covers and remove debris from catch basins. French drains should be flushed with a garden hose to ensure water flows freely to the outlet. Clogged French drains can cause water to pool around your foundation increasing hydrostatic pressure on your slab.
Check the outlet of your French drain system. It should be clear of debris and positioned to direct water away from your home. If the outlet is underwater during normal conditions your system needs professional evaluation. A properly functioning French drain system can handle several inches of rainfall per hour reducing the load on the S&WB drainage system.
Water Heater Protection During Storms
Your water heater contains several gallons of water that can become contaminated if your home’s supply lines are compromised. Turn off the cold water supply valve to your water heater before a storm. This prevents contaminated water from entering the tank. If you have a gas water heater turn the gas control valve to the pilot position. For electric units switch off the circuit breaker.
Secure your water heater to wall studs using approved strapping kits. During high winds an unsecured water heater can tip causing gas line breaks or flooding. If your water heater is located in a low area consider elevating it on a platform. This prevents potential contamination from floor-level flooding.
Boil Water Advisory Preparedness
After a major storm the S&WB often issues boil water advisories due to potential contamination of the municipal supply. Store at least one gallon of potable water per person per day for three days. Keep unscented household bleach on hand for emergency water treatment. Eight drops of bleach per gallon of water can make contaminated water safe for drinking if boiled water isn’t available.
After the storm passes and before turning your water back on flush all supply lines. Open all cold water faucets and let them run for five minutes. This clears any stagnant or contaminated water from your pipes. Replace all faucet aerators and showerheads that may have trapped sediment or contaminants..

Post-Hurricane Plumbing Safety Inspection
Once the storm passes and it’s safe to move around your property conduct a thorough plumbing inspection. Check for visible leaks around all fixtures and exposed pipes. Look for water stains on ceilings and walls that might indicate hidden leaks. If you smell gas or sewage leave the area immediately and call emergency services.

Test all drains by running water and watching for proper drainage. Slow draining or gurgling sounds indicate potential blockages from debris or system damage. Check your water meter reading when all fixtures are off. If the meter continues to run you have a hidden leak that needs immediate attention.
Inspect your water heater for signs of damage. Look for rust, water accumulation around the base, or unusual noises when the burner ignites. If your home experienced flooding do not turn on gas or electric water heaters until they’ve been inspected by a professional.
